ISO 14001 Aspect and Impact analysis process

If your focus is the environmental assessment of a corporate office, I recommend that you consider two levels:

• The office level; and
• The office decisions that influence other units 

About a) consider the typical office aspects like energy and water consumption, waste generation.

About b) consider for example decisions about business travel, supplier and investment selection, with an environmental component like CO2 emissions.
